Abstract

The invention provides a comprehensive pipe rack fire compartment ventilation system. The comprehensive pipe rack fire compartment ventilation system comprises a sensor set, an ampere meter, a fire detector, a controller and an inducement blower. The sensor set is used for collecting inlet temperature of a fire compartment and base layer temperature of soil. The ampere meter is used for obtaining an average current value of cables in a fire zone. The fire detector is used for obtaining a fire signal in the fire compartment. The controller is used for outputting a corresponding control signal according to the fire signal obtained by the fire detector and a preset temperature set value curve of an outlet of the fire compartment under the corresponding circumstance and then changing the output frequency of a frequency converter, and thus the rotation speed of the inducement blower is controlled. The inducement blower is arranged at the outlet of the fire compartment. The rotation speed V of the inducement blower is determined by the output frequency of the frequency converter. According to the comprehensive pipe rack fire compartment ventilation system, the problem that a routine control method cannot meet the temperature control precision of a comprehensive pipe rack outlet, the reaction speed and automation are solved so that the comprehensive pipe rack fire compartment ventilation system can control the temperature of the comprehensive pipe rack outlet accurately, fast and automatically, and thus the ventilation effect of a comprehensive pipe rack can be improved significantly.

Description

technical field

[0001] The invention belongs to the field of municipal engineering, and specifically designs a ventilation system and a control method for a fireproof partition of a comprehensive utility gallery. Background technique

[0002] The comprehensive pipe gallery is a municipal infrastructure that can accommodate various underground pipelines such as water supply and drainage, electricity, communication, and gas. Entering the 21st century, my country's urbanization process is accelerating, and the pressure of urban environment improvement and the shortage of various public resources is increasing day by day. As a comprehensive carrier of urban municipal pipelines, underground comprehensive utility corridors can realize the intensification and integration of various municipal pipelines. Unified and standardized construction and management can change the current situation of criss-crossing, disorganized and frequent maintenance of urban underground pipelines, which ha...
